It's a little bit difficult to say what fascism in Germany was since the economies of the U.S. and U.K. had many of those same controls in place because it was war time, and because these countries had all just recovered from the Great Depression, so there was a lot of government command-control of the economies.

So was it really fascism, or just attempted pragmatism because Germany was in such a squeeze, both in terms of economically and war being waged close to its borders and being surrounded on two fronts? I mean, had the U.S. government found their country in that same position, they might have implemented some very similar controls.

So things in Germany were not perfect, but much of that tends to be inherent in any form of socialism or partially centrally-planned economy.
Many of the people still felt things had improved for them compared to how things were before. And a lot of the people at that time were afraid of communism (not entirely without good reason, as would become evident a decade or two later) so were willing to put up with all the bad things, seeing it as "the lesser of two evils".

As for Germany not being able to be self-sufficient, that's not entirely reflective of a failure on the part of the government. It was a developed country, already with an industrial base. Much higher population density than in the East. Typically those types of countries are reliant on bringing in resources from outside. That video also neglects to mention the German technological advance of developing synthetic rubber derived from oil, which was a significant thing. Germany is also a colder country, so not surprising a developed and (despite the Depression) more affluent country would be importing in vegetables from other warmer countries. All in all, I think that video drew a few unjustified conclusions.

And the end of the video, he talks about people wanting to leave the Romanian ethno-state for more multicultural countries elsewhere.
The issue with this, these other countries are multicultural in the first place because they were/are more affluent (populations from other countries want to go there). The speaker in the video is making the logical fallacy of confusing causation with correlation.

Arguably the second fallacy he makes is assuming the Romanian ethno-state is actually representative of the "all-white" state Nazi Germany held up as an ideal (when, as he well knows, the Nazis made a differentiation between ethnicities in Europe and did not simply see them as all "white"). (It's true Germany allied with Romania, but that was more out of convenience)

South Korean band BTS has been criticised for “mocking the past” by the Simon Wiesenthal Center. Probably Koreans need a proper education on modern European history. Some members of BTS are clearly sympathetic towards the Nazis and the Korean band recently appeared on stage at a concert with a symbol “eerily similar” to the Nazi swastika.

The Simon Wiesenthal Center, based in Los Angeles, issued a harshly worded statement criticising the record-breaking band for “mocking the past” and urged members to apologise to both Nazi victims and Japan.

“Wearing a T-shirt in Japan mocking the victims of the Nagasaki A-bomb, is just the latest incident of this band mocking the past,” said Rabbi Abraham Cooper, its associate dean.

The statement also referred to photography of members wearing hats with Nazi logos believed to be taken in 2014 as well as footage of flags waved by the band on stage at a concert which were reportedly “eerily similar” to the Nazi swastika.

“It goes without saying that this group, which was invited to speak at the UN, owes the people of Japan and the victims of the Nazism an apology,” he added in the statement.
